About some exact solutions of nonlinear system of the differential equations describing three-party elections. (English) Zbl 1398.34065

From the abstract: In the paper nonlinear mathematical model describing dynamics of voters pro-governmental and two opposition parties (three selective subjects, the coalitions) is offered.
In some special cases of constancy or variability of coefficients of model, exact analytical solutions are found and theorems which show conditions under which the pro-government party will lose the next elections are proved.
